Filed:

Mar 22, 1991

Appl. No.:

7/673594

Inventors:

Chris M. Jamison - Indianapolis IN
Gregg S. LaMontagne - Austin TX

Assignee:

Ransburg Corporation - Indianapolis IN

International Classification:

B05B 502
F04B 4312

US Classification:

239690

Abstract:

A coating material dispensing system comprises an electrostatic high potential supply having an output terminal on which the supply maintains a high electrostatic potential, a source of coating material, and a dispenser for dispensing the coating material. The output terminal is coupled to the dispenser to supply potential to the coating material dispensed by the dispenser. A peristaltic device couples the dispenser to the source of coating material. The peristaltic device has a length of resilient conduit and contactors for movably contacting the length of resilient conduit at multiple contact points for substantially dividing the coating material in the peristaltic device into discrete slugs of coating material substantially to interrupt the electrical path through the coating material from the terminal to the coating material source. Thhe peristaltic device includes an inlet end for coupling to the source of coating material. The length of resilient conduit has a first inside transverse sectional area at a first location along its length when it is filled with coating material at the first location and a second inside transverse sectional area larger than the first at a second location along its length further from the inlet end than the first location when it is filled with coating material at the second location.

Abstract:

A coating material dispensing system includes an electrostatic high potential supply having an output terminal on which the supply maintains a high electrostatic potential, a source of coating material, a dispenser for dispensing the coating material, and appropriate fluid and electric circuits for coupling the dispenser to the source of coating material and the output terminal to the dispenser to supply potential to the coating material dispensed by the dispenser. The fluid circuit coupling the dispenser to the source of coating material includes a peristaltic voltage block having multiple coils of a resilient conduit and a rotor for supporting an element for contacting each coil at multiple contact points. The peristaltic voltage block substantially divides the flow of coating material to the dispenser into discrete slugs of coating material substantially to interrupt the electrical path through the coating material from the terminal to the coating material supply.

Assignee:

Ransburg Corporation - Indianapolis IN

International Classification:

B05B 1502

US Classification:

239110

Abstract:

A device for atomizing and dispensing a first liquid coating material onto a first group of one or more articles to be coated by the first coating material and then for dispensing a second liquid coating material onto a second group of one or more articles to be coated by the second coating material. The device includes at least one atomizer providing a first flow rate of the first and second coating materials required for high quality atomization of the first and second coating materials, and a second outlet providing a second and substantially greater flow rate of the first and second coating materials and lower quality atomization than the first atomizer, or no atomization. A first conduit couples the second outlet to the first atomizer. A second conduit couples the first atomizer to a source of fluid to be dispensed. A valve controls the flow of liquid to the second outlet.

US Classification:

239600

Abstract:

A quick disconnect for a coating material dispensing device includes a passageway through which coating material is supplied from a supply conduit for dispensing. The supply conduit includes a first region along its length provided with a surrounding O-ring. The passageway includes a sidewall providing a second region along its length in which the first region resides when the supply conduit is positioned in a use orientation in the dispensing device. The second region compresses the O-ring into fluid-tight sealing orientation against the passageway sidewall in the second region when the supply conduit is inserted into the passageway into its use orientation.

International Classification:

B05B 504

US Classification:

239703

Abstract:

A system for atomizing and dispensing powder comprises a fluidized powder bed for entraining the powder fluidized in a bearing air stream, a dispenser, and a motor for rotating the dispenser. The dispenser has a somewhat bell-shaped interior. The motor has an output shaft having a first passageway extending lengthwise thereof. A feed tube extends through the first passageway. The fluidized powder is fed to an end of the feed tube passageway remote from the dispenser to be supplied through the feed tube to the interior as the motor rotates the dispenser. A diffuser is mounted within the interior. A discharge slot is defined between the dispenser and an edge of the diffuser. The feed tube is mounted so that it does not rotate with the output shaft. The diffuser includes a back side facing the interior and bounded by the edge. The back side includes a generally part-spherical concavity into which the fluidized powder is directed from the feed tube.
